Oscar Trelles

Author of The Human OS Manual.

I study how people operate under pressure, and how energy, clarity, behavior, recovery, adaptation, and healthspan change when the conditions around them change.

The Human OS Manual launches October 2026. Its central argument is simple: self-improvement fails when you ignore the system running underneath.

The Human OS Manual is my forthcoming book, launching October 2026.

Why self-improvement fails when you ignore the system running underneath it.

It explains why self-improvement often fails when sleep, stress, work, habits, health, recovery, aging, mindset, relationships, and environment are treated as separate problems.

The book offers a systems framework for understanding the operating conditions underneath energy, behavior, recovery, adaptation, and healthspan.
